Google (NASDAQ:GOOG) has added a new feature to its search engine: the ability to also look through users’ private Gmail account for anything related to the search request. For example, searching “Amazon” (NASDAQ:AMZN) could bring up e-mails related to shipping orders, or searching “flight” could bring up a travel itinerary, The Associated Press reports.

Here are five things to know about the new search engine:

Google is, at this point, still only testing the feature. It will initially be available to 1 million Gmail users who sign up at http://g.co/searchtrial.

The mail search results will be shown to the right of the main results or at the top of the search page.

Google hopes to give all Gmail users the option of plugging their accounts into the main search engine after the test is finished and feedback is received.

The company did say that it is willing to display information from other email services down the road.

Google’s ultimate goal is to personalize the search engine experience so much that it can answer users’ questions to a point not previously thought possible.
